Objective:
Develop a Cell Phone
to Landline System
• Basic cell phone functionality from a
landline phone
– Make cell phone calls from your
home phone
– Answer cell phone calls from
your home phone
• Additional features
– Voicemail
– Speed dial
• Can replace or co-exist with
existing landline service
–Pay only one monthly phone bill
Design:
CellSync connects a cell phone to a landline phone. CellSync
allows users to send and receive cell phone calls from their
landline phone. The CellSync method uses the Asterisk
software, a Telephone Network Interface Card (TNIC), and
Bluetooth to route cell phone calls to a landline phone.

Asterisk is a telephony networking engine and toolkit.
The Telephone Network Interface Card (TNIC)
communicates between the landline phone network and
Asterisk. Chan-Mobile communicates between a cell
phone and Asterisk via Bluetooth. CellSync uses chanmobile to route cell phone calls to Asterisk, which then
routes calls to a landline phone.

The CellSync method is executed on our prototype
system shown to the left. The CellSync menu is shown to
the top right. A mock-up of a marketable CellSync
product is shown to the right.
Before calling the user must:
1. Connect landline service to the FXO (Green) port on the system
2. Connect landline phone to the FXS (Red) port on the system
3. Add cell phone to system profile using CellSync menu
4. Pair cell phone and system using the pin number 1234
For incoming calls:
1. Incoming calls are recognized by Asterisk
2. Asterisk recognizes the FXO port the call originated from
(Cell phone or Landline)
4. Asterisk sends ringing signal to the landline phone
5. Call continues as normal
6. Unanswered calls are redirected to voicemail
7. Calls to cell phone redirect to cell phone voicemail; calls to
landline redirect to system voicemail
For outgoing calls:
1. Dialing 9 + 10 digit phone number initiates cell phone call
2. Dialing 6 + 10 digit phone number initiates landline call
3. Cell phone calls are routed through the cell phone via Bluetooth
4. Landline calls are routed through the FXO port on the TNIC
5. Call continues as normal
